longer than they are wide
longer than they are wide
at different degrees of offset
Term 3 of 43
the load block weight is considered part of the weight of the _______
load to be lifted, not including rigging
total weight of the crane including its own structure
the maximum load capacity of the crane itself
the weight of the rigging equipment used in lifting
,Term 4 of 43
if the boom length falls between values listed on the load chart, the operator should use the
capacity rating for the
the average load radius based on previous lifts
next longer load radius to be compensated for the boom length
shorter load radius to ensure safety during lifting
the maximum boom length allowed for the crane
Term 5 of 43
during critical lift operation, the operator must obey a(n) _______ signal at all times
emergency stop
load signal
safety check
lift command
Term 6 of 43

pendulum theory
resonance effect
Term 7 of 43
interpolation is permitted is determining load capacities
True
False
,Term 8 of 43
in preparing for multiple-crane lifting, the load blocks of each crane have to be positioned
relative to the loads center of gravity using the formula ________
deducted from
the ground to the center of the boom point sheaves
(net capacity crane one) x A =

cranes are typically built to be
longer than they are wide
steel erection or multiple-crane lifts
example is vertebrae
next longer load radius to be compensated for the boom length

, Term 12 of 43
leverage is defined as
the power applied to a lever to cause the load to move
the weight of the lever itself
